Very nice for working with many projects.

A must have if you like to organise your stuff.

boosts productivity. awesome tool. thanks a lot.

My productivity has improved so much with being able to have different tab groups for work, personal, research, volunteer work, etc! Great way to get in the zone and not be distracted by other parts of your life.
I have had it crash a few times, but when I close firefox and reopen it, all my tabs are still there so it's not a big deal. Be aware that it makes backups in your Downloads directory (starting with STG); you can delete the old ones at any time or disable this in settings.

Takes a bit of learning to figure out, but once you're comfortable using it, it's great! Love that it hides the tab group you're not using: less temptation to switch tasks.

works well, feels like using safari tab groups sidebar

Simple Tab Groups? I suppose it's simple to use but it's anything but simple in functionality! Wow. What can I say? Firefox actually works, unlike Safari and this extension actually works, unlike Safari's tab groups. This will change how I work and browse. Thanks!

It would be great if the developer could add "subgroup" functionality to the extension. I right now have 65 groups open lol. I would love to be able to put each groups into categories. For example., if I am doing research on topic X, Y, and Z, and have groups named X,Y, and Z (respectively), I would love to be able to put all three groups under one group called "research". Hope that makes sense. I'd hazard a guess that this shouldn't be too difficult to implement. Many thanks to the developer for this extension, it has made research so much easier.
